If you look at the websites it's clear that both Lencarta and Pixapro ones come complete with a 4cm Honeycomb grid.
The beauty dishes however are not identical, the Pixapro ones only have 8 supporting rods, which doesn't control the light direction and distribution anywhere near as well as the Lencarta ones, which have 16 supporting rods. The Lencarta diffusers are also much better (for use in softbox mode) but they have the same honeycomb.
